While searching for steampunk stuff to populate the Spymaster’s lab, I discovered that old clock movements are as beautiful and sculpturally fascinating to me as the innards of stereos and record players. I got a cuckoo clock movement for like $20 shipped. It’s about 3.5 x 3.5 x 1 inches, pleasingly harmonious and balanced in its asymmetry. I think I might get some more. They’re just so cool!
